Gravity Core
On this page
The Gravity Core provides artificial gravity for Zile City. Its enormous ring-shaped structure surrounds the base of the Central Tower, with an open center through which the tower rises.
Structure
The core is a toroidal installation. Flowing graviton currents cover its inner walls, while tramway corridors provide routes for transit and maintenance within the structure.
The precise dimensions and field-control mechanisms remain unspecified. The core and tower are connected parts of the central landscape but are distinct locations.
Conditions during the crisis
The Mastermind Crisis breaks the interior into unstable fields of moving wreckage. Platforms, plates, and sections of corridor drift and tumble, making the environment itself a source of danger.
Moving through the damaged interior requires attention to the motion of the surroundings as well as to hostile machines. Unstable fields and shifting wreckage make routes unreliable. Its eventual restoration and exact operating limits remain unsettled.
